In The Machine Stops‚ E.M. Forster projects life years from now where people live underground with extreme technological advances. Also‚ people live separated in little rooms where they find a variety of buttons they can press in order to perform any task they desire. They do not communicate with people face to face as often as we do now. Without a doubt‚ their society is very different from ours. All of the inhabitants are used to living along with the Machine and it is hard for them to imagine

When I try to apply this metaphor to real life‚ the first thing that comes to mind is the assembly line inside a factory. To create a product each member has their role on the assembly line and there isn’t much deviation from the set process otherwise the product may be unpredictable.
